Public Toilet

We got frustrated witnessing the devastation that the haphazard dumping of human waste causes to public health and the environment.

We got tired of seeing broken-down and abandoned wastewater and fecal sludge treatment plants in cities throughout the developing world.

We stopped believing that billing low-income households is the best — or only — way to finance sanitation.

And thus emerged Waste Enterprisers. We were founded in Ghana in 2010 and transferred operations to Kenya in 2013.

Our values drive our decisions. We’re committed to forging massive improvements in urban sanitation and to fostering a positive, dynamic, and rewarding company culture.
